Electrophysiological recordings (electroencephalograms, somatosensory-evoked potentials, cognitive-evoked potentials) were made in five patients during acupuncture-induced analgesia for removal of a thyroid tumor. The electrophysiological measures were unchanged during the operation. Acupuncture's modes of action in producing analgesia are not revealed in this study.
